I apologize if the devs were developing this/mentioned this.

After the guilds have been out and enlarged, i think there should be some type of "Guild war" avaliable

There should be a specific town for guilds, each guild having a... um.. idk.. Main house? and others try to conquer it. To make it fair, there should be a people limit on the guild war (ex. member 10 vs. Member 30 unacceptable). Each time a guild is conquered, the guild which conquered it should have a stat mark on how many deaths/kills it had.

This war could be made either by pvp on the members on the guild... protect the guilds main building in the town square.

Members can chill in the building and have a "No fight" sig on, which disables other guilds to attack it. If a guild is attacked Members will immediately be messaged. In order for the people which are farming not be distracted, the #1 rule should be "can not enter fight when in stage", therefor the remaining alliances in the guild can fight, and the hardcore farmers in peace.
